Description
The European Laboratory for High Energy Physics CERN in Geneva, Switzerland, is a major consumer of energy with almost 90% of the electric energy being used for the operation of the accelerators. Efforts are being made to further increase the energy efficiency and to reduce the consumption. Practical work concentrates on 3 areas: the CERN campus, the accelerator chain, and re-use of waste heat. A coherent energy concept is implemented for major renovations and when constructing new buildings. Equipment and cycles of the accelerators are dynamically switched on/off according to needs. Most of the electric energy is finally disposed in cooling towers as low grade waste heat, which can possibly be re-used for heating buildings.
